| titleOfInvention | Process for producing polymer having reduced low-polymerization products and unreacted products |
| abstract | (57) [Summary] [Object] The present invention provides a method for producing a water-soluble polymer which is excellent in tackiness, thickening property and cohesiveness and in which a small amount of unpolymerized substances and unreacted substances are small. [Structure] In producing a water-soluble polymer having a low molecular weight of 10,000 or less and reduced unreacted materials, (1) When the polymerization rate reaches 90%, the viscosity of the polymerization system becomes 1 A step of carrying out an aqueous solution polymerization so as to be at least 0,000 cps, A water-soluble polymer comprising a step of (2) continuously polymerizing until the polymerization rate exceeds 95%, and a step of (3) ultrafiltering the obtained water-soluble polymer. Production method. |
